Starrett Crankshaft Distortion Dial or Strain Gage with Balancing Attachment - Yellow Face, 61-458mm Range, .02mm Graduation, 0-50-0 Dial Reading - 696MZ

An ideal gauge for checking bearing alignment or shaft deflection without dismantling the engine. Useful as a strain gauge on engine frames. This inside measuring gauge checks the distortion of crankshaft webs. This distortion bears a direct relation to existing misalignment or excessive bearing wear. The gauge makes it possible to check bearing alignment or undue shaft deflection without dismantling the engine. Used on all diesel engine shafts and the center crankshafts on any type of engine or compressor, the gauge can also be applied as a strain gauge on engine frames while the engine is operating. A comparison of readings taken at top and bottom positions indicates any misalignment of cylinder and frame which results in local over-stress and eventual cracking of the frame neck. With a special spring tension in the dial indicator, the gauge is self-sustaining in any position without sacrificing necessary rigidity, thus leaving the operators hands free. The contact points are conical, with an approximate 60 degree included angle, hardened and ground to a sharp point, and will stay in place on 45 degree surfaces.

• Engine Maintenance Simplified - Effortlessly check bearing alignment and shaft deflection with 696MZ Gage, designed to measure without dismantling the engine. Ideal for maintaining optimal engine performance.
• Dual-Function Tool - Not just a measuring device, it also serves as a strain gage on engine frames, detecting direct relation to existing misalignment that could lead to over-stress and frame damage during engine operation.
• Wide Measuring Range - With a 61-458mm range and a 4mm dial indicator movement. This tool is equipped for a variety of engines sizes, enhanced by 10 rods and one extension furnished.
• Durable And Accurate - This gage features a movable bezel to adjust the dial in relation to the hand and a non-breakable crystal, ensuring precise readings and a long-lasting reliable tool.
• The Standard for Excellence - Proudly made in the USA, Starrett combines over 140 years of American heritage and innovation with globally sourced materials to deliver exceptional quality tools and products.
